Note 293 — Chapter X · THE EDWARDIAN CASTLE AND THE CONCENTRIC PLAN

This was not founded by the Crown, like the great castles of North Wales, but, like Caerphilly, was a private foundation. It passed by marriage, early in the fourteenth century, into the possession of the house of Lancaster. Some of the most important English castles—e.g., Kenilworth, Knaresborough, Lancaster, Lincoln, Pontefract, and Pickering—came at various times into the possession of this royal house, and, at the accession of Henry IV., became castles of the Crown as seized of the duchy of Lancaster.
